Sports equipment

ABSTRACT

A kind of sports equipment which comprises a sole and an upper is revealed. The sole is provided with a peripheral wall projecting upward from a periphery of the sole and a mounting groove formed on an outer surface of the peripheral wall. The upper is arranged at the sole and a periphery of a bottom of the upper is bent inward to form a connection portion which is mounted into the mounting groove on the peripheral wall of the sole correspondingly. The connection portion of the upper and the peripheral wall of the sole are sewn and connected by a sewing thread while the sewing thread is located at the inward-bent connection portion of the upper so that the sewing thread will not be exposed. Thereby the upper and the sole are connected more firmly and aesthetics of the sports equipment is also improved.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a kind of sports equipment, especiallyto a kind of sports equipment not only with higher connection stabilityof an upper and a sole but also having improved aesthetics of the wholesports equipment.

Description of Related Art

Generally, an upper and a sole of sports footwear are adhered to eachother by adhesives such as super glue and water-based adhesive. In orderto connect the upper with the sole, complicated processes such as theupper and the sole are coated with adhesives and pressed multiple timesare required. The processes are tedious and time-consuming. During theprocesses, poisonous gas may be occurred due to the adhesives used suchas the super glue and the water-based adhesive. The poisonous gas notonly damages respiratory tracts of working staff but also results inenvironmental pollution. Moreover, adhesives are easy to have overflowissues during application. This has negative effects on aesthetics ofthe sports footwear after drying of the adhesives. The adhesives alsohave other problems such as ageing and unglued over time, which resultin separation between the sole and the upper. Thus there is room forimprovement.

SUMMARY OF THE INVENTION

Therefore, it is a primary object of the present invention is to providea kind of sports equipment in which not only connection stability of anupper and a sole is efficiently increased, aesthetics of the wholesports equipment is also improved.

In order to achieve the above object, a kind of sports equipmentaccording to the present invention includes a sole and an upper isrevealed. The sole consists of a peripheral wall projecting upward froma periphery of the sole and a mounting groove formed on an outer surfaceof the peripheral wall. The upper is disposed on the sole and aperiphery of a bottom of the upper is bent inward to form a connectionportion which is mounted into the mounting groove on the peripheral wallof the sole correspondingly. The connection portion of the upper and theperipheral wall of the sole are sewn and connected by a sewing threadwhile the sewing thread is located at the inward-bent connection portionof the upper so that the sewing thread will not be exposed. Thereby theupper and the sole are connected more firmly and aesthetics of the wholesports equipment is also improved.

BRIEF DESCRIPTION OF THE DRAWINGS

The structure and the technical means adopted by the present inventionto achieve the above and other objects can be best understood byreferring to the following detailed description of the preferredembodiments and the accompanying drawings, wherein:

FIG. 1 is an exploded view of an embodiment according to the presentinvention;

FIG. 2 is a partial enlarged exploded view of a section of an embodimentaccording to the present invention;

FIG. 3 is a sectional view of an embodiment according to the presentinvention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Refer to FIG. 1 , FIG. 2 and FIG. 3 , a kind of sports equipment mainlyincludes a sole 1, a support member 2, and an upper 3.

The sole 1 consists of a peripheral wall 11 projecting upward from andformed on a periphery of the sole 1, a cavity 12 which is a closed spaceformed within the peripheral wall 11 and a top surface of the sole 1,and a mounting groove 13 formed on are outer surface of the peripheralwall 11.

The support member 2 which is an elastic body is mounted in the cavity12 of the sole 1 and a top surface of the support member 2 and anopening of the cavity 12 are at the same level.

The upper 3 is arranged at the sole 1 and provided with a connectionportion 31 which is formed by a periphery of a bottom of the upper 3bent inward and mounted into the mounting groove 13 on the peripheralwall 11 of the sole 1 correspondingly. The connection portion 31 of theupper 3 and the peripheral wall 11 of the sole 1 are connected with eachother by sewing with a sewing thread 4. The sewing thread 4 is locatedat the inward-bent connection portion 31 of the upper 3 so that thesewing thread 4 will not be exposed.

Compared with the connection between the upper 3 and the sole 1 byadhesives such as super glue and water-based adhesive available now, theupper 3 and the sole 1 of the present sports equipment are sewn andconnected by the sewing thread 4. Thus the upper 3 and the sole 1 areconnected more firmly, without easily separated from each other due toconstant pulling and stress. Moreover, the sewing thread 4 is embeddedin the upper 3 without being exposed so that aesthetics of the sportsequipment is improved. Stains or residuals caused by dried adhesivespill or overflow after connecting the upper 3 with the sole 1 byadhesives can also be avoided.

Furthermore, the design of connection between the upper 3 and the sole 1by using the sewing thread 4 simplifies the complicated processes forconnecting the upper 3 with the sole 1 used now during which the upper 3and the sole 1 are coated with adhesives and pressed multiple times.Thus the production efficiency is improved and the production cost isreduced. Other problems such as damages to respiratory system of workersor environmental pollution caused by poisonous gas released duringapplication of the adhesives (super glue, water-based adhesive, etc.)can also be avoided.

In summary, the present invention has the following advantages:

1. The upper and the sole of the present sports equipment are connectedby the sewing thread which is embedded in the upper without beingexposed. Thus not only the upper and the sole are connected more firmly,aesthetics of the sports equipment is also improved.2. Since the upper and the sole of the present sports equipment areconnected by the sewing thread, complicated processes such as multipletimes of coating and lamination are no more required. Thereby productionprocesses are simplified, production efficiency is increased andproduction cost is reduced.3. The upper and the sole of the present sports equipment are connectedby the sewing thread so that no more adhesives are needed. Thus theproblems generated during application of the adhesives including superglue and water-based adhesive such as poisonous gas released which notonly damages respiratory tracts of working staff but also causesenvironmental pollution can be avoided.4. A support member is mounted in the cavity of the sole to keep the topsurface of the support member and the opening of the cavity at the samelevel. Thereby not only the strength of the sole is improved, shockresistance and wearing comfort are also provided while wearing orwalking.

Additional advantages and modifications will readily occur to thoseskilled in the art. Therefore, the invention in its broader aspects isnot limited to the specific details, and representative devices shownand described herein. Accordingly, various modifications may be madewithout departing from the spirit or scope of the general inventiveconcept as defined by the appended claims and their equivalent.
